I claim:

1. A log roller having in combination a land travelling vehicle and a narrow inclined jaw pro- Jecting forwardly from said vehicle means for varying the angularity of said jaw with relation to the ground together with means for raising and lowering said jaw while said vehicle is being oneratcd.

2. A log rolling device consisting of a land travelling vehicle in combination with an arch hinged to said vehicle forwardly thereof, a Jaw projecting forwardly and downwardly from the forward end of said arch means for varying the .angularity between said law and arch and means for raising and lowering the forward end of said arch.

3. A log rolling mechanism having in combination a land travelling vehicle having hinged to the sides thereof and extending around its forward end an arch, a cable winding mechanism actuated by the prime mover of said land travelling unit adapted to raise and lower said arch, an inclined jaw having its forward side serrated extending in front of the forward end of said arch and having means for adjusting the angularity of said jaw with relation to said arch.

4. In a log turning device the combination of a land travelling vehicle having an arched frame extending around the front thereof and hinged to the sides thereof, a stationary arched frame extending above said land travelling vehicle and supported thereby, a cable winding mechanism on said vehicle having its cable supported by said last mentioned arch and attached to the first mentioned arch for the purpose of controlling the elevation thereof and a log engaging Jaw attached to and extending forwardly from the forward end of said first mentioned arch.
